The underlying user authentication infrastructure has completely changed with the switch from GRUF to PAS in the latest Plone release. As a result, CMFMember, a widely used tool that allows for more sophisticated member management within Plone 2.1 and earlier, no longer works with Plone 2.5. Have no fear, however. There are a couple of new products, one called membrane and one called remember, that are providing all of the functionality of CMFMember and more. This session provides an overview of the greater Plone member management landscape, focusing primarily on what -- exactly -- these new products do and how they can be used as a basis for custom applications.
